Yes I have always found it odd that every monster in an adventure stories seems to hate the main characters in the story and to instantly attack them. Its nice to see that some monsters don't feel the need to commit suicide.

and has in his / her pockets a level of gold equal to your level. Later in the game when petty thieves are carrying around an amount of gold equal to a small house. Why steal? When we can start a bank!

No I mean the place inside the labyrinth where Randulf and Colleen entered by teleportation. No reason for mages or townsguards to follow them there through the portal. I guess an Otyugh could smell she left her last meal there. Of course it would have to go through a swarm of carnivorous fairies, but maybe those wouldn't attack anything that smells like an Otyugh.
